Method:
Put 1/2 a teaspoon yeast in a cup and add 1 teaspoon warm water to it. Cover it and leave it for 15 minutes in a warm place (near a heater/inside an oven with very mild temperature/near the stove). Then add 1/2 teaspoon sugar and stir it once or twice. Let it ferment for one hour.

Now sieve the flour in a bowl and add salt to it. Next add butter and mix with your hands so it resembles bread crumbs. Then add a beaten egg and the yeast mixture to it and kneed well. Now add milk little by little as needed until it becomes a smooth dough. The dough must not stick to the fingers.

Place the dough in a greased bowl, and cover it with a wet cloth and leave in a warm place for 2 or 3 hours until doubled in size.

Once it has risen you could start making the buns. Divide dough into pieces. Roll into balls and cover with the wet cloth for 5 minutes.

Flatten each ball into a circle with about 6” diameter on a well floured surface. Next stretch the edges of the circle another inch or so, leaving the center a little thick. Put about 1 tbsp of filling into the center. Fold into a triangle. See picture below.

Place on a greased baking tray with the folded side facing down. Brush with the beaten egg. Cover and let rest for 10 minutes. Bake at 375 degrees F for 20-25 minutes or until golden brown.
